Every time I turn on or restart my pc. I am having this sudden glitch right after the windows logo. It appears and goes away but it is happening everytime. I have tried disabling overclocking but it didn't solve the issue.

if the corrupted image is actually an OS issue that Startup Repair just couldn't detect;
the Refresh or Reset options should fix it.

if choosing an option that fully resets or re-installs Windows just keep in mind that any offline data or personal files would be lost.
backing them up first or choosing one of Windows "keep my personal files" options would be recommended.
 
I actually did a clean reinstall. Finished just now. I am still having the issue. Guess it is a hardware issue. What would you suggest?

UPDATE:
I swapped the graphics card and RAM. Problem still exists. Must be the motherboard. Is there any way to fix?

try a different display first and see if the image persists.

there's a possibility that it is a corrupt company image that the board is trying to add into the boot sequence, though this would usually display before Windows starts to load.
do you have a custom User avatar for your Microsoft/Windows account? this could also possibly be causing an issue.

i would contact ASUS support and send them a link to the video. maybe they could shed some light on what is supposed to be shown at that point, if it's a company logo or not.
if it is an issue with the board they should offer RMA services.
 
No, I don't have a custom avatar.
I have created a technical support request ticket in Asus support site. I'll wait for their response.

And I tried connecting my display to the onboard HDMI port. Surprisingly, I didn't see the glitch on boot. Could it be that the pci slot is damaged? When I checked I could not find any physical damage. All pins are ok.

you connected to an integrated GPU's HDMI port on the I/O panel, not the dedicated PCIe GPU?
if yes, and it is being caused by some type of damage, maybe it is just a GPU HDMI port going bad causing this single odd instance for some reason. try the GPU's other ports; DisplayPorts, etc.

if the PCIe port where the dedicated GPU is located was damaged enough to cause graphical errors, you would see them in much more instances than just the boot sequence.
but, to try totally ruling it out, run some graphics stress tests and see if any noticeable issue(s) arise.
 
Yes I connected to the motherboard's hdmi port(I/O panel with the USB/audio/lan ports). The Graphics card should be fine because I checked with another Graphics card and still had the issue.
I ran some gpu stess tests using benchmarking tools. There was a very minor lag for a second, but other than that I didn't find any major issue nor any graphical error.
 
is definitely odd.
search for any BIOS update(s) to see if it may be a common issue that has been corrected or just something off with the current version.

after ruling out everything else; i would just guess there is something about the particular setup that doesn't agree with the display(for that one split second every time).
hopefully ASUS will get back with you with some more information regarding what may be the cause.
